Healthy HVAC Systems

Periodic maintenance of HVAC (Heating, Ventilation and Air-conditioning) systems can be performed by a service and maintenance company specializing in such systems. The maintenance technician can do a systems health check which involves overall physical inspection, equipment cleaning and performing preventive maintenance diagnostic tests for checking system response to prescribed settings (relative to ambient temperatures) and initiate any required corrective measures.

Equipment life, though can be extended by the owner thru the following activities:

Utilization of better filters. High-efficiency pleated filters have electrostatic charge which works like a magnet to trap the tiniest particle (even those that can carry bacteria). Visit our site and check it out!

- Filter replacement at least every three months. Pet dander, though, may cause more frequent replacement. A filter that looks black or clogged may have to be replaced at once. Note, however, that there are washable filters, allowing re-use and prolonging the filter life, making the need to replace unnecessary for several more months. Washable filters, however, must be checked relative to the cooling performance of the HVAC system.

- Ensuring manufacturer specifications for clearance around outdoor air conditioning units and heat pumps are met for proper air circulation. Avoid storing materials near these units that impede air flow. Grass clippings during lawn-mowing should not discharge into the unit.

Monthly check of visible refrigeration insulation (and drainage) and repairing damaged or missing lines. Refrigerant loss will definitely affect air conditioning maintenance system cooling performance. Drain blockages could impair unit performance while leaks from fan coil unit drains could damage ceilings and walls.

- Ensuring outdoor air-conditioning units and heat pumps remain installed on firm and level ground or pads, with any isolation springs, anchor bolts or screws properly fastened.

Air supply and return for HVAC systems are usually facilitated through duct-work. Most duct-work systems have been designed with a particular air circulation capacity and corresponding equipment rating. Air circulates thru the ducts five or seven times a day carrying dust and debris with it. System efficiency can be threatened by the gunk build-up. There may be a need to clean ducts when there are visible clogs of dust, cobwebs, debris or noticeable particles blowing out of supply diffusers, as well as visible mold on the inside surfaces of ducts. If the area is accessible, the owner may just proceed with a vacuum cleaner and other appropriate cleaning tools, taking care not to cause the duct to rust or be damaged.

The expertise and equipment of a professional service technician, however, may be required for areas beyond the owner's reach. Vermin could also enter duct-work and the service technician can help locate and seal entry points to prevent further infestation of ducts (although pest control may be the province of other specialists).

Longer HVAC system life and performance in accordance to the system was designed can be achieved through regular equipment maintenance and keeping the duct-work clean. However, if performance parameters have changed, then the system may have to be upgraded to meet the new requirements.
